The another portion independentlyi of'the yoke 2 head is carried by a movable carrier whichby the frames or Standard St ereof. When.

55 i ll -a lever o yoke. the steam 1s promoted through the lower no buck as shown in Fig. 1, the portion carried b the'yoke is a normally stationary ad ustaliile shoulder 19 as a set screw and the portion carried by the frame 5 consists of motion transmitting mechanism. This motion transmitting mechanism comprises a push rod 20 carried by the standard and arranged in the path of the shoulder or set screw 19, a bell crank lever 21 pivoted at 22 to the frame, one arm thereof being connected to the push rod 20 and the other arm to one end of a link 23, the other end of which is connected to one arm of a bell crank lever 24 pivoted at 25 between its ends to the frame, the other arm of this hell crank lever 24 coacting with a valve opening member 26 which pushes against the valve stem 15. This valve opening member 26 is also operator operated in order that the steam may be projected at any time through the garment or independently of any movement of the head 1, and, as here illustrated, it is connected by a link 27 to a pedal 28, the link 27 having a bifurcated portion or yoke ortion 29 therein with which the arm of t e bell crank 24 coacts. The push rod 20 is guided in a suitable bracket 30 and a returning spring 31 is interposed between the bracket and the head 32 on the upper end of the rod 20. Obviously, as the head is pulled down, the set screw or shoulder 19 will engage the head 32 of the push rod 20 and depress the push rod against the action of the s ring 31, and hence actuate the bell crank ever 21, link 23, bell crank lever 24:, valve opener 26 and valve stem 15.

Preferably, the valve 0 ens before the head 2 is completely closed and closes before the head is completely closed, and this action is brought about b a ratcheting device between the bell cran r 24 and the valve opener 20. This ratcheting device in Fi 2, is shown as a pin or shoulder 33 ivote at 34 in the yoke 29 and is normally eld from pivotal movement upwardly by shouldering against the flat surface at 35 of the oke, the pin being heldagainst this flat sur ace by a spring 36. The arm of the bell crank lever 24 engages the underside of this pin 33 and hence during the closing of the press, this bell crank lever 24 pushes up on the in 33 thus opening the valve in the case 11 ei'ore the press is closed and before the press is com letely closed, the bell crank lever ratcliets past or oti' the end of the pin 33 permittin the valve to be closed y its spring beIore the head is completely closed.

During the opening movement of the press, the bell crank lever 24 in moving in a retrograde direction, ratchets downwardly past the pin 33 by moving the pin 33 on its pivot 34 against the spring 36. The intermediate point at which the valve is open is determined by the set screw 19.

In Figs. 3 and 4, the shoulder or set screw which corres onds to the set screw 19 is designated 3% The ush rod 38 and the hell crank levers 39 and 40 which correspond to the bell crank levers 21 and 24 of Fig. 1 are pivoted to the yoke 6 at 41 and 42 respectivel 43 designates the returning spring corresponding to the spring 31. 44 is the guide and 45 the head at the end of the push rod 38 which coacts with the set screw 37.

46 designates the link connecting the bell crank levers. The bell crank lever 40 is the valve opening member and coacts or pushes against the upper end of the valve stem 15 and is also provided with a handle 47 by means of which the valve may be opened manually.

In the construction shown in Figs. 3 and 4, the ratchet device is rovided in the link 46 between the bell cran s 39 and 40 and as here shown the link 46 is formed with a shoulder 48 for coacting with one arm of the bell crank lever 40 and is also formed with a slot 49 in the rear of the shoulder 48, the end of the link in front of the shoulder 48 riding on the end of the coacting arm of the bell crank lever 40. The valve casing 12 is located in a suitable steam conduit 50 movable with the head 2 which conduit supplies steam to the perforations 9 and chamber 10 of the head 2.

In operation, during the closing of the press head, the head 45 at the end of the push rod 38 engages the set screw 37 actuating the bell crank lever 39 and ushing the link 46 forwardlv so that the s oulder 48 thereon engages t e coacting arm of the bell crank or valve 0 ener 40, thus opening the valve and 1101 ing it open until the link 46 passes forwardly far enough to permit the coacting arm of the bell crank 40 to ratchet over the shoulder or rather to permit the shoulder 48 to ratchet over the coact-ing arm of the bell crank 40 so that such arm passes into the slot 49 and ermits the spring 14 to close the valve. is occurs before the prem head is fully closed so that the valve is closed when the press is closed and further so that the steamin operation takes place just prior to the comp ete closing of the press.

During the opening of the head 2 and during rearward movement of the link 46, the coacting arm of the bell crank lever 40 ratchets back into a position in front of the shoulder 48 and in so doing, the end thereof which coacts with the valve stem 17 moves away from the valve.

In either exemplification of my invention, the steaming operation takes place automatically before the press is completely closed and stops before the head is completely closed and further the valve is not opened during the opening of the press. Furthermore, the operator can steam the garment in the usual way opening the valve.

by manually or pedally What I claim is:

1. In-a pressing machine, a frame, cooperating pressing elements comprising a buck, a head movable toward and from the buck, alever pivoted to the frame and carrying the head, one of the pressing elements being formed with perforations through its pressing face, a conduit for supplying a medium under pressure to said perforations, a normally closed, spring pressed valve in the conduit, and means for opening the valve including a part carried by the lever and a part carried by the frame, the former being movable into engagement with the latter as the head. coacts with the buck.

2. In a pressing machine, a frame, cooperating pressing elements comprising a buck, a head, movable toward and from the buck, a lever ivoted to the frame and carrying the hea one of the pressing elements being formed with erforations through its pressing face, a con uit for supplying a medium under pressureto said perforations, a normally closed, spring pressed valve in the conduit, means for opening the valve comprising an actuator carried by the lever,

. and motion transmitting part carried by the buck, a lever frame and connected to the valve, the motion transmitting part being normally spaced apart from the actuator and arranged to be engaged thereby as the head coacts with the buck.

3. In a pressing machine a frame, co-

4. In a pressing machine a frame, co-

operating pressing elements comprising a valve, the motion transmitting part bein normally spaced apart from the actuator an arranged to be engaged thereby as 'the head coacts with the buck, and an operating member connected to the valve to actuate it independently of the automatic means.

5. In a pressing machine a frame, cooperating pressing elements comprising a buck, a head movable toward and from the buck, a lever pivoted to the frame and carrying the head, one of the pressing elements being formed with perforations through its pressing face, a conduit for supplying the medium under pressure to, said perforations, a normally closed, spring pressed valve in the conduit, and means for openin the valve comprising an actuator part an a spring pressed motion transmitting part connected to the valve, one of said parts being carried by the lever and the other by the frame, and an operatin member connected to the motion transmittin means to open the valve independently 0 said automatic means.

In testimony whereof, I have hereunto signed my name, at Chicago, in thecounty of Cook, and in the State of Illinois, this 9th day of- September, 1925.
